Application March 18, 1957, Serial No. 646,866

1 Claim. (Cl. 20-53) This application relates to ventilator constructions, sometimes known as windows and particularly to windows which are known in the trade as basement windows.

A particular object of the present invention is to provide for such ventilator constructions a novel latch arrangement.

The foregoing object and others will best be understood upon reference to the appended drawing which shows a preferred embodiment of the invention with such drawing being best understood upon reference to the specification which follows.

In this drawing:

Fig. 1 is a small scale diagrammatic elevation view of the ventilator construction as a whole;

Fig. 2 is an elevation view of one part of the construction to larger scale;

Fig. 3 is a side section view as if on line 3-3 of Fig. 2 showing the parts in the sash closed position;

Fig. 4 is a view like Fig. 3 but showing the parts just after latch release and just prior to the sash open position and somewhat diagrammatically.

Referring to the drawing it will be observed that it shows a ventilator or window construction comprising a stationary frame F and a ventilator or window sash S. The frame is of Z section and the sash is of L section, common in the trade.

In accordance with conventional design, the lower horizontal members of both the frame and the sash are formed to enable the sash to be inserted into or removed from the frame and likewise to enable the sash to he swung to and from the frame along the lower edge of the sash as an axis.

In addition, means are provided to stop the swing of the sash away from the frame. Such means may be of any desired form; as shown, it comprises slotted side arms 18 pivoted at 20 to the frame and receiving pins 22 of the sash in slots 23, with enlargements 24 which enable sash removal.

The foregoing is all old and well known. To it are added the latches which form the specific improvement hereof.

The latches The automatically operating latches 40 are formed of sheet metal and are disposed in the vertical side spaces 41 between the vertical side members of the sash and the vertical side members of the frame. The latches have angular slanting mounting slots 48 and the frame side members have cooperating pins or rivets 46 in the slots 48 whereby the latches are mounted on the frame side members to slide up and down obliquely in the spaces 41.

The latches are L-shaped and have angular latching slots 56 slanting and opening down and towards the l nited States Patent The lower ends of the latches are formed as exposed handles 60.

Operation The operation of the latches is as follows. Normally the latches are down in the full line position shown in Fig. 3' and are maintained in that position by their weight, as slight as that is, there being considerable freedom of sliding movement between the latches and the pins 46 which mount the latches. When it is desired to swing the ventilator sash towards the frame for closing the ventilator, the sash is swung closed whereupon the latching pins 58 of the sash engage rounded earns 62 of the latches to raise the latches automatically and permit the pins 58 to pass by ends 62 and enter slots 56. Thereupon the latches drop automatically according to the slant of Slot 48 so that the latching slots ride down along the latching pins 58. Due to the 'slant of surfaces 63 of these slot portions 56, and also due to the slant of the mounting slots 48 of the latches, the downward movement of the latches causes the latches themselves to move towards the frame and at the same time causes the sash to be biased towards the frame for more effective sealing.

For releasing the latches it is merely necessary to move the latches upwardly by lifting the handles 60 of such latches. Thereupon the first part of the movement of the latches biases the sash away from the frame for breaking whatever seal may have developed. This action is due to the engagement of the slanted edge 64 with pins 58. The upward movement of the latches releases the sash to permit it to swing automatically and outwardly to the extent permitted by the means 18.

It will be observed that the construction. herein shown comprises automatically acting latches. The latches automatically receive and automatically latch the sash when the sash is swung to the frame for closing and no manual manipulation of the latches is necessary during the closing movements. Likewise, the latches automatically seal the sash when it is swung closed without manual actuation of the latches. The only manual action necessary is to raise the latches. This breaks any seal that may have formed and releases the sash automatically and the sash swings automatically to its open position.

It will further be observed that the latches function for sealing and breaking seal during the sash closing and sash opening movements. Sealing is effected automatically by the dropping of the latches after the sash is swung closed. Seal breaking is accomplished automatically simply by the manual raising of the latches.

Now having described the automatic latch construction herein disclosed, reference should be had the claim which follows.

I claim:

In a ventilator construction comprising a stationary frame, a movable sash pivotally mounted therein to swing on the lower horizontal edge of the sash as an axis to and from the frame, the improvement which comprises automatically operating latches in the vertical side spaces between the vertical side members of the sash and frame, with such latches having angular mounting slots slanting down and towards the frame, the frame members having pins in such angular mounting slots which cooperate .so that thetlatches .slide up anddown obliquely in such spaces, down towards and up away from the frame, the latches also having angular latching slots slanting and opening downwardly and towards the sash, the latter having pins on the vertical side sash members positioned to enter such latching slots and be biased towards the frame when the latches are moved down for latching action, and for retaining the sash in and sealed against the frame, and handles on such latches exposed to enable the latches to he moved manually down for latching .and .up for releasing, vthe mountingslo-ts and the latching slots being at angles to true vertical and to one another to slant oppositely.
